                  Pharmaceuticals. Please go ahead.

Gina Brazier:     Good morning and welcome to the Millennium/COR conference call
                  discussing our merger announced this morning. I'm Gina
                  Brazier, director of investor relations at Millennium. With me
                  today from Millennium are Mark Levin, chief executive officer;
                  Kevin Starr, executive vice president, business operations and
                  chief financial officer; John Maraganore, senior vice
                  president, strategic product development; and Claire Midgley,
                  vice president of corporate communications. From COR are
                  Vaughn Kailiean, chief executive officer of COR, and Dr.
                  Charles Homcy, executive vice president of research and
                  development.

                  The agenda for the call is as follows: Mark Levin and Vaughn
                  Kailiean will discuss the merger and their view of the future
                  of the company. Vaughn will also provide updated financial
                  guidance for COR, and Kevin will review the terms of the
                  transaction. We will then take your questions.

                  Before I turn the call over to Mark, I'd like to state that
                  during this call we will be making forward-looking statements,
                  including statements regarding the proposed transaction
                  between Millennium and COR, the expected timetable for
                  completing this transaction, future financial and operating
                  results, benefits and synergies of the transaction, future
                  opportunities for the combined companies, discovery, and
                  development of products, potential acquisitions, strategic
                  alliances, and intellectual property, and any other statements
                  about Millennium or COR management's future expectations,
                  beliefs, goals, plans, or prospects constitute forward-looking
                  statements within the meaning of the Private Securities
                  Litigation Reform Act of 1995. Any statements that are not
                  statements of historical fact include statements containing
                  the words "believe," "plan," "anticipate," "expects,"
                  "estimates," and similar expressions should also be considered
                  to be forward-looking statements. There are a number of
                  important factors that could cause actual results or events to
                  differ materially from those indicated by such forward-looking
                  statements including the inability to consummate the
                  transaction; the inability of Millennium to successfully
                  integrate COR's operations and employees; the inability to
                  realize anticipated synergies and cost savings; adverse
                  results in drug discovery and clinical development processes;
                  failure to obtain patent protection for discoveries;
                  commercial limitations opposed by patents owned or controlled
                  by third parties; dependence upon future alliance partners to
                  develop and commercialize products and services based on our
                  work; difficulties or delays in obtaining regulatory approval
                  to market products and services resulting from the company's
                  combined development effort; the requirements of substantial
                  funding to conduct research and development and to expand
                  commercialization activities and the other factors described

                  Mark?

Mark Levin:       Thanks, Gina. As you can imagine, we are tremendously
                  enthusiastic about our announcement this morning regarding the
                  merger between Millennium and COR. The merger is a key
                  milestone in Millennium's vision to build a major
                  biopharmaceutical company, a company transcending the limits
                  of medicine to the development of breakthrough products.
                  Products based on the cause and pathways of human diseases to
                  make a significant difference in people's lives. Very
                  importantly, this vision is shared by Millennium and COR. Let
                  me now move on to reviewing the highlights of this
                  transaction.

                  First, this merger is the most important biopharmaceutical
                  merger in the history of the industry. We are bringing
                  together two of the most successful companies in the industry
                  to realize our plan of developing the first and only truly
                  gene-to-patient enterprise. The numbers alone tell a
                  compelling story. The joint company will have 1,200 people in
                  R&D, 140 people in marketing and sales, and planned annual R&D
                  budget of over $500 million in 2002.

                  With our new commercial platform and cardiovascular franchise,
                  we will move even more aggressively to bring our later-stage
                  compound to the clinic and on to the marketplace. These
                  compounds include exciting opportunities in cardiovascular
                  disease, oncology, inflammation, and metabolic disease. This
                  also adds to our ability to license in later-stage molecules
                  from the outside into our marketing, development, and sales
                  operation.

                  Secondly, the combined Millennium/COR merger will have four
                  franchise disease areas: cardiovascular, oncology,
                  inflammation, and metabolic disease. Again, the numbers tell
                  and exciting story. Our four franchises have combined sales in
                  the U.S. alone of over $30 billion in opportunity. The
                  combined company year-end 2001 will have three products on the
                  market, one product marketed by the company, nine molecules in
                  the clinic, one I&D filed with trials to start in the near
                  term, and positioned to put three to four new molecular
                  entities into the clinic in 2002. Equally important to our
                  development pipeline will be the combined depth of our
                  discovery pipeline -- dozens of molecules and pre-clinical and
                  lead optimization with hundreds of targets to inter-screen
                  [sp] over the next several years in both small molecule and
                  antibody therapeutics. In short, we have the pipeline to make
                  it happen.

                  Third, the products in this pipeline represent two
                  breakthroughs in the treatment of disease: Integrilin -- it's
                  the leading intravenous platelet aggregation inhibitor with
                  over $225 million in 2001 sales and growing at over 30 percent
                  a year. Although this product has taken a pause this quarter,
                  I am confident that the molecule will continue to take patient
                  share and grow 30 percent annually over the next several
                  years. Campath -- an important antibody that we developed with
                  and recently licensed to our partners on the market for the
                  treatment of refractory chronic lymphocytic leukemia.
                  Melastatin -- a proof-of-principal personalized medicine
                  diagnostic product to predict the likelihood of metastasis for
                  melanoma, also licensed to our partner. LDP341 -- as many of
                  you know, 341 is our premier oncology compound based on
                  proteosome inhibition, a novel mechanism for treating cancer.
                  We are the only company in the clinic with a compound



                                                      MILLENNIUM PHARMACEUTICALS
                                                                  Res. #20069850
                                                          Moderator:  Mark Levin
                                                December 6, 2001 / 7:00 a.m.  MT
                                                                          Page 3


                  based on this novel and promising mechanism, and we are in
                  trial for both liquid and solid tumors. 341 has shown very
                  striking early results in multiple myeloma and various solid
                  tumors, some of which we will be discussing at next week's ASH
                  [sp] meeting. J591 -- this is an antibody to prostate-specific
                  membrane antigen widely regarded as the best and most specific
                  target for prostate cancer therapy. We have seen significant
                  reduction in PSA levels and tumor shrinkage in early studies.

                  In addition, we have important molecules in the clinic and a
                  variety of other important disease areas including asthma,
                  ulceritic colitis, Crohn's disease, stroke, and, of course,
                  MLN4760, our new obesity compound from our genomics-driven
                  platform which just entered the clinic.

                  The COR pipeline includes a number of cutting-edge compounds
                  that match well with this portfolio of novel products. COR's
                  receptor tyrosine [sp] kynase [sp] program will have its first
                  product in the clinic very early next year, and the pipeline
                  also includes emerging new products such as olefactor 10A
                  inhibitor, which has the potential to treat the many patients
                  with deep vein thrombosis and arterial fibrillation who are
                  under-served by current therapies.

                  The implications of this deep pipeline are even more exciting.
                  Next year we will have additional compounds entering the
                  clinic in oncology, inflammation, and obesity.

                  Fourthly, COR brings to Millennium a seasoned and extremely
                  well-regarded team. Without unduly embarrassing Vaughn and
                  Charles here on the call with me today, let me just say that
                  we are not alone in recognizing that this team is one of the
                  finest that the biotechnology industry has ever produced. We
                  are truly proud that they have seen fit to join forces with
                  us, and I'm sure all of you in the financial community will
                  agree with me on this one.

                  Both Vaughn and Charles will have continuing prominent roles,
                  senior roles, in the company today. Vaughn will join
                  Millennium's board as vice chairperson and in addition will
                  become responsible for commercial operations in the
                  therapeutic area businesses. Charles will become president of
                  R&D and lead our 1,200-person-strong effort in research and
                  development. Both Vaughn and Charles will report to me, along
                  with Kevin Starr. I'm also delighted today to announce that
                  Kevin has been promoted to chief operating officer effective
                  immediately, based on his outstanding performance.

                  Following completion of the merger, we expect to add four new
                  COR board members to the Millennium board of director,
                  including Vaughn Kailiean, current CEO of COR; Sean Coughlin
                  [sp], a COR co-founder and professor of medicine at the
                  University of California-San Francisco; Ernest Morio [sp], a
                  COR director whose distinguished career has included, among
                  other accomplishments, CEO positions at Alza [sp] and Glaxxo;
                  and Ginger Graham, group chairman at Gidon [sp]. In addition
                  to the board and senior management team, COR adds to
                  Millennium's commercial infrastructure a seasoned development
                  and commercialization team with a track record of excellence.
                  The COR 109-person sales force has had widely recognized
                  success in marketing Integrilin. In the face of stiff
                  competition from the marketing powerhouses at Lilly and Merck,
                  the COR sales team built an over 50 percent market share in
                  its class.

                  COR also brings the clinical trial organization to Millennium
                  with proven track record capabilities of launching and
                  managing large-scale, multi-center studies from Phase I to
                  Phase IV. This group, in combination with Millennium's
                  existing clinical organization,

                                                December 6, 2001 / 7:00 a.m.  MT
                                                                          Page 4


                  will provide the resources to effectively manage our growing
                  clinical pipeline from all four franchise areas.

                  As I reflect on the strength, passion, and commitment of the
                  combined leadership, science and business, I tell you with
                  great confidence that this is an incredible team, unmatched in
                  the industry. A team that can build the next major
                  biopharmaceutical company.

                  And finally, our vision to realize the promise of the genome
                  by developing products based on molecular medicine and
                  personalized medicine continues to evolve with the merger. At
                  Millennium, the novel technologies of the life sciences are
                  coming together. Our expertise in genomics with our ability to
                  identify and validate new targets with our elucidation of the
                  synergies among these genes, targets, and biological pathways,
                  will give us the ability to develop truly molecular medicines
                  to treat disease.

                  It is clear, for example, that our crucial relationships in
                  the pathway relating to the causes of both cardiovascular and
                  metabolic disease as well as the relationships of both
                  oncology and cardiovascular disease to inflammation. We firmly
                  believe that as an understanding of these targets and pathways
                  and the related markers in their association with disease that
                  fuels Millennium's leadership in personalized medicine -- the
                  right gene, the right target, the right pathways, to attack
                  the right disease for the right person.

                  To wrap up, we at Millennium have a commitment to build the
                  leading biopharmaceutical company where strategic mergers have
                  always been a very important aspect of this strategy. The COR
                  merger will bring together two quality organizations with
                  synergistic capabilities across all aspects of both companies.
                  It brings Millennium into the arena of sales and marketing
                  with Integrilin, the number-one product in its class.

                  Both teams share a strong science-based culture and a
                  tremendous passion for our vision. We are very much looking
                  forward to combining forces as we accelerate our progress to
                  building the next major new biopharmaceutical player.

                  I will now turn the call over to our new colleague, Vaughn
                  Kailiean.

Vaughn Kailiean:  Thank you, Mark, and it's an absolute delight to be here today
                  with Mark to announce this merger. Those of you who have been
                  following COR for a long time know our passion for excellence,
                  know our absolute insistence on having the right and the very
                  best people, and from the very first time that we sat and
                  talked with Mark and Mark's organization, we recognize their
                  excellence, but I think one of the hallmarks of this coming
                  together is that every time we met, it got better. There were
                  not rough spots-- there were obviously rough spots in any
                  negotiation but, you know, at the end of every discussion, we
                  felt better about the deal than we did coming in, and we're
                  hitting the market here absolutely with a great rush,
                  recognizing that Mark has built a great team and Charlie and I
                  and the COR organization are very, very envious of the
                  tremendous organization that you've built, and we're just
                  delighted to be able to make a significant contribution to it.

                  I wanted to give you a few -- I want to spend a few minutes
                  now giving you our perspective on this merger. First of all,
                  as you know, we at COR are very, very proud to have built our
                  business basically from scratch as a research start-up in 1988
                  to a fully integrated commercial organization with an R&D and
                  science-driven pipeline of novel therapeutic products,
                  including one on the market only 12 years later. We view this
                  merger with Millennium as an entirely natural next step in
                  COR's evolution. Our pipeline requires us to gain access to
                  just the resources Millennium has available in its franchise

                                                                  Res. #20069850
                                                          Moderator:  Mark Levin
                                                December 6, 2001 / 7:00 a.m.  MT
                                                                          Page 5


                  areas, and we believe that our joint and expanded
                  infrastructure will optimize the development and marketing of
                  our pipeline.

                  Together, we'll have the critical mass of novel products and
                  the development and commercial organization to develop them
                  and bring them to the market with true force. As you can tell
                  from the development of our oncology program at COR, we have
                  long been committed to the strategy of developing a pipeline
                  of products against a number of molecular targets. The
                  combination of cardiovascular disease and oncology alone are
                  the two major diseases in the developed world, and the
                  combination of Millennium's and COR's efforts in these two
                  areas will make us a major player in therapeutic development
                  and commercialization.

                  In addition, as Mark has so kindly pointed out, our sales
                  force has competed successfully, very successfully, in an
                  extremely competitive environment, and we believe its value
                  will be leveraged across all of the franchise areas at COR.
                  This is a true area of synergy for the two companies.

                  Finally, let me just say a few words about Integrilin. As you
                  saw from this morning's press release, our sales expectations
                  for Integrilin for 2001 have been revised, but with a strong
                  caveat that we continue to see a long-term positive outlook in
                  growth. We're adjusting our 2001 annual worldwide sales
                  forecast to 225 to 230 million, which will result in earnings
                  per share of break-even to modest profitability in the fourth
                  quarter and, as a result, modest profitability for the year
                  ending 2001.

                  This adjustment is due to a slowdown in the market growth,
                  which has been obvious to all of us, and we've been discussing
                  during the second half of 2001 as compared to the first half,
                  but we expect this slowdown to be transient.

                  In spite of this, Integrilin patient market share grew to over
                  51 percent in the second half of 2001, and this growth in
                  itself may be understated due to a recent finding that some
                  intervential [sp] cardiologists who are switching from Riopro
                  [sp] to Integrilin may have been limiting their duration of
                  therapy to only 12 hours post-PCI as opposed to the
                  recommended 18 to 24 hours.

                  As I said earlier, however, the bottom line is that we fully
                  believe and we're fully committed to the long-term growth of
                  Integrilin, and we're putting in place specific initiatives to
                  spur Integrilin growth, and these include a major conversion
                  effort with hospital administrators, which demonstrates a
                  favorable cost and pharmacoeconomic profile of Integrilin
                  relative to competitors building off the pharmacoeconomic data
                  that was presented at the recent American Heart Association
                  meeting.

                  A new emphasis on new findings from Integrilin that
                  demonstrate more favorable benefits with Integrilin when it's
                  dosed for at least 18 hours post-PCI. That was also presented
                  at the recent American Heart Association meeting, and we've
                  got a focus on establishing a broad-scale, early-use in an
                  early aggressive therapy of Integrilin and unstable angina by
                  promoting adherence to the new ACCA-AHA management guidelines
                  in a quality improvement initiative called Crusade in over 600
                  hospitals in which we will enroll over 60,000 patients.

                  And finally, to further grow the marketplace here, we are
                  going to pursue Phase II, III, and IV clinical trials of
                  Integrilin in ST segment elevation MI, CAM [sp] surgery, and
                  peripheral arterial disease.

                  To sum up, just let me say that Charles and I and the rest of
                  the COR team are very, very much looking forward to helping
                  build Millennium into a major, the major, new
                  biopharmaceutical player.

                  With that, it's now Kevin's turn, and Kevin is out in
                  California, so Kevin, I'll let Kevin give the terms of the
                  transaction. Kevin?

Kevin Starr:      Thanks, Vaughn. Good morning, everybody. First, let me just
                  walk through the terms of the transaction. Some of this is in
                  the press release. I'd like to just go through it
                  comprehensively.

                  So, as you know, Millennium Pharmaceuticals will be acquiring
                  COR in a stock-for-stock exchange that's valued at
                  approximately $2 billion, in which COR shareholders will
                  receive 0.9873 shares of newly issued Millennium stock for
                  each share of COR stock. Based on last night's closing price,
                  this would result in an applied purchase price of $35 per
                  share for COR stock. This is a 77 percent premium to
                  yesterday's close, and a 64 percent premium to the trailing
                  30-day average. The combined company will keep the Millennium
                  Pharmaceutical's name and will be headquartered in Cambridge,
                  Mass. As a result of the transaction, we expect to issue 58
                  million shares of Millennium stock. The merger agreement has
                  been approved by both boards at Millennium and COR, and the
                  transaction is subject to shareholder vote at both companies,
                  as well as HSR clearance. We do expect the transaction to
                  close in the first quarter of 2002.

                  Also, as you know, COR currently has approximately $600
                  million in outstanding convertible debentures, so under the
                  terms of the merger, Millennium is required to put forward a
                  tender offer for those converts that are in the money after
                  closing. It is our intent to retire as much of that
                  convertible debt as possible, as soon after the close as
                  possible.

                  As far as guidance goes, because we did not expect the
                  transaction to close before the end of the year, this merger
                  does not affect Millennium's 2001 financials and our 2001
                  guidance does remain unchanged. As a reminder, we expect
                  revenue for 2001 to be approximately $240 million, with a net
                  operating loss of approximately $125 million. For 2002, we can
                  only say now that we expect Integrilin, as Vaughn mentioned --
                  Integrilin sales to be a large growth story, with growth to be
                  at least 30 percent, and we expect Millennium revenues to grow
                  as well over the next several years.

                  Our management teams will use the next few weeks to determine
                  the financial profile of the combined company and we'll be
                  providing that full guidance on 2002 and beyond for Millennium
                  and COR as well as the combined entity, as part of our press
                  release in our 2001 quarterly financial call, or annual
                  financial call, during the week of January 21st.

                  We do expect that this merger will be an important step in
                  driving us towards our goal of profitability in 2003, or 2004,
                  but importantly, this will not be the only step, as you will
                  see us continue to in-license and acquire promising products
                  and companies and promote organic growth from our pipeline as
                  we move forward in building the company.

                  Before I turn the call back over to Mark, I'd like to spend a
                  minute giving some of my perspective on COR and our decision
                  to merge. As you know, strategic mergers and acquisition
                  activity has always been a key part of our strategy to create
                  a major new biopharmaceutical player that we've been planning.
                  In order to execute on this M&A strategy, we've assembled one
                  of the finest teams in the industry that has reviewed
                  literally thousands of potential opportunities. In each one of
                  these cases, we've set an

                                                                          Page 7


                  extremely high bar in terms of the quality of science, the
                  magnitude of the opportunity, the strategic fit within our own
                  therapeutic area, and of course, the people. And the COR
                  acquisition rose to the top, meeting every one of our
                  stringent criteria. The Millennium team, moreover, has the
                  industry's strongest track record at integrating or
                  transforming acquisitions. We can point very proudly to
                  acquisitions and mergers with Chemgenics [sp], Lucasite [sp],
                  CDC [sp], and now to COR. We're very much looking forward to
                  working with the COR team as we progress towards building our
                  common goals.

                  So now let me turn the call over to Mark.

M. Levin:         Thanks, Kevin, and congratulations on your promotion to chief
                  operating officer. Great job.

K. Starr:         Thanks.

M. Levin:         Before we take your questions, let me take a minute and put
                  the merger in perspective. This is a milestone in executing on
                  our ambitious business plan to build an integrated research
                  and development-rich commercial biopharmaceutical company. We
                  have a proven track record in structuring unique business
                  alliances, including mergers such as this, 50-50 partnerships
                  with big pharma, in-licensing of products and targets, and
                  access to novel drug discovery and development technologies.

                  Looking forward, the new commercial capabilities and hospital
                  sales force resulting from the COR merger will enable
                  Millennium to maximize our existing pipeline and expand even
                  further our in-licensing efforts.

                  Let me leave you with some of what we will accomplish over the
                  next 90 days alone. First, provide 341 preliminary phase II
                  data in multiple-myloma, presented at the ASH meeting next
                  week. Secondly, initiate the 6,000-patient advanced MI phase
                  III trial of Integrilin and facilitated angioplasty for ST
                  segment elevation MI. Thirdly, initiate additional phase I
                  combination trials of 341 and Taxateer [sp] in solid tumors.
                  Fourthly, initiate phase I trials of CT5-- I'm sorry,
                  CT535518, a first-in-class RTK inhibitor in acute myloid [sp]
                  leukemia. And continued phase [sp] of transforming
                  relationships, including mergers, acquisitions, in-licensing,
                  and partnerships.

                  So as you can see, we've got a lot of exciting news events
                  coming up in the next 90 days, which we'll certainly keep you
                  up to date on.

                  And finally, I'd like to say for all of us at Millennium what
                  an outstanding job Vaughn, Charles, and their team have done
                  in building one of the pre-eminent biotechnology companies and
                  how proud we are to be continuing this journey with them of
                  building the next biopharmaceutical company.

                  With that, we're now ready for questions.  Operator?

M. Levin:         Good morning, Mike.

Operator:         Just one moment.

Mike King:        Can you hear me?  I'm not on mute.

M. Levin:         Good morning, Mike.

M. King:          I got cut off.

M. Levin:         We can hear you.

M. King:          I'm sorry about that; I'm fine. I think the person who's
                  probably the happiest in all of this is Vaughn's mom.

V. Kailiean:      That's true; you're right. She doesn't know yet.

M. King:          Oh, she doesn't?

V. Kailiean:      No.

M. King:          Shame on you, shame on you. My questions really are more of a
                  financial nature. I just-- Kevin, can you just discuss the
                  valuation premium for us, please, if you would, and what kind
                  of comparables you took into account when deciding on the
                  acquisition price. And I know that you're going to give
                  guidance on, you know, the model of the combined companies
                  going forward, but I thought if you could comment just in
                  general, about potential cost savings, as well as things like
                  the charges for in-process R&D and amortization. Thanks.

K. Starr:         Sure. So first, question, Mike, was on the premium. We, as we
                  do in all of our cases when we look at mergers and
                  acquisitions and bringing people and pipelines together, look
                  at it through a number of different lenses, and the primary
                  lens we look at it is how it affects our ability to build the
                  company that we've articulated over the next five, 10, and 15
                  years, and to do that, we do discounted cash flow analysis of
                  the product pipeline on a probablized basis, and that
                  includes, of course, Integrilin in our anticipated sales
                  growth, for Integrilin, as we do see that market continue to
                  expand. I mentioned the 30-percent-plus growth, certainly in
                  the near term, and over a sustained period of time.

                  We also looked at some of the promising pre-clinical and
                  near-term clinical candidates, like the RTK program and factor
                  10A, looked at those through a probablized lens, as they will
                  come through the pipeline going forward. We also counted,
                  importantly, some of the synergies between what Millennium was
                  going to have to build to aggressively move into the
                  commercial arena for programs like 341 over the next several
                  years and what the synergies with the COR team could do to
                  help us build avoid-- some avoidance of build in some of those
                  areas. So we looked at discounted cash flow, we looked at
                  overall influences to how it could accelerate our pipeline. We
                  certainly looked at trading averages over the 30, 60, 90, and
                  longer period of time, and on all fronts, it came out to the
                  $35 number, which we offered to the COR shareholders, and the
                  board of directors, which was accepted last night. That did
                  result in a 77 percent spot premium and a 64 percent over the
                  recent trailing average. We felt that was solidly right in the
                  mark of fair value for both Millennium shareholders and for
                  COR shareholders and what we can do to build this company
                  together.

                  In terms of guidance, I did mention we're not going to give
                  specific financial guidance until the end of January at our
                  annual call. I will say a couple of things about synergies. We
                  don't look at this merger in the classic major pharmaceutical
                  merger sense, where we look at hundreds of people or tens or
                  hundreds of millions of dollars of near-term savings, with
                  overlapping organizations. What we've actually found with the
                  two groups are very complementary organizations. We will have
                  a handful of overlapping functions, which we'll work through
                  during some transitional roles. The biggest synergies we see
                  and the biggest cost savings we see are build avoidance for
                  both companies. You know, we looked at COR as a stand-alone
                  enterprise and where they were going, to develop oncology
                  expertise, to actually, in their plans, to add some more
                  genomics capabilities and early stage discovery capabilities.
                  We can help them avoid that build from a stand-alone basis.
                  Likewise, I mentioned the commercial side, where we were
                  aggressively pursuing plans to get ready for 341 and its
                  potential over the next couple of years. This has a major
                  impact of how we look at that over the next several years. So,
                  we see some real synergies at how we would build the company
                  together that are much more efficient than we would have done
                  as a stand-alone.

M. Levin:         Thanks, Mike.

Operator:         Maykin Ho with Goldman, Sachs, please proceed with your
                  question.

Maykin Ho:        Hi. I have a question mostly on the R&D program -- can you
                  expand a little bit on the synergy in the cardiovascular area?
                  I know you've been working on it at Millennium for quite a
                  while; obviously at COR it's the major focus. And then also
                  talk about the receptor [inaudible] kynase program.

M. Levin:         Yet, Maykin, let me just give you a little bit of an overview,
                  and John and Vaughn should comment on this also. In general,
                  as you know, many, many years ago, seven years ago, actually,
                  Millennium started working in the cardiovascular area, and
                  it's always been a driving force. We have major programs in
                  arteriosclerosis, and also in congestive heart failure, and
                  those are programs with Buyer and Lilly, and we've built up an
                  extraordinary team inside, and so as we got talking to Vaughn
                  and Charles, we've always believed that we have to build a
                  cardiovascular franchise inside Millennium, based on the fact
                  that it dominates the franchise areas in the world today, with
                  over $40 billion in sales alone, in the cardiovascular area.
                  So as we look at the overall synergies, Integrilin can come to
                  market -- certainly Integrilin now in clinical trials to
                  actually add to its market share in other applications outside
                  the current approved applications. New molecules that COR [sp]
                  is developing in the platelet area, the thrombosis area, the
                  10A program, the ADP program, and also basic programs in
                  research and genomics behind this, which actually are
                  extraordinarily exciting, that Jamie Toppler [sp] and the team
                  at COR are working on.

                  The synergy between what they're doing there and our programs,
                  we believe, are very significant, not just in the
                  cardiovascular area -- as we all know, the overlap between
                  cardiovascular, obesity, and diabetes is very significant, and
                  we see some tremendous synergies, not only in cardiovascular,
                  but obesity and diabetes, for the long-term. Let me ask John
                  and Vaughn also to add to that.

John Maraganore:  Well, I think, Mark, you said it -- you said it very nicely. I
                  think there clearly are underlying commonalities of both tapa
                  physiology [sp] as well as molecular mechanisms that go
                  between cardiovascular and also with inflammation and
                  metabolis disease. There

                                                                  Res. #20069850
                                                          Moderator:  Mark Levin
                                                December 6, 2001 / 7:00 a.m.  MT
                                                                         Page 10



                  are also market synergies as well, as we look at obesity and
                  diabetes, where, in fact, major morbidities associated with
                  those diseases include cardiovascular disease.

                  So there's clearly both market synergies, there are clearly
                  molecular synergies, and that's an important aspect of how
                  we've looked at this, going forward.

V. Kailiean:      And let me -- this is Vaughn. Let me just sort of talk -- take
                  it from John and move it further downstream. Commercially,
                  there are tremendous synergies, as we have our hospitals sales
                  force positioning in all the tertiary care, major teaching
                  hospitals in the United States as well as the major -- as well
                  as some of the major community centers in the United States.
                  Since we're sitting there already with a number-one product
                  and a number-one reputation, as the oncology program of
                  Millennium rolls forward, the first and natural place for it
                  to go is on top of our hospital sales force, in their hands,
                  into those institutions, and then if you think beyond that,
                  our own program, our own RTK program, which I'm going to ask
                  Charles to comment on in just a second, then builds on the
                  back of the LDP 341 synergy and then finally, after that, our
                  own 10A program, comes in. So, it's a wonderful, rolling
                  synergy, all the way from science, all the way out to
                  commercialization.

                  For a little bit more detail on the RTK program, which you
                  asked about, Ken, I'd like to ask Charles to give you a little
                  bit of an update on that, and where we stand vis a vis our IND
                  and our first clinical applications.

C. Homcy:         Yes, we're very much on time to enter the clinic in the first
                  quarter of next year, and this is a inhibitor of FLT III,
                  which is a growth factor receptor that's mutated in about 30
                  percent of patients, to a constitively [sp] active form.
                  Patients with AML. So this is very much like the story of
                  Gleveck, with the Abelson [sp] gene, that's mutated in that
                  disease. So, this comes out of our, originally, out of our PGF
                  receptor program, so this compound is an orally active, highly
                  bio-available, very potent inhibitor of FLT III, and so we're
                  very excited about the potential for that in AML. But from
                  that program, we have a very large chemistry now that will
                  provide additional leads for producing compounds for other
                  kinds of cancer, with other kinds of activities, in terms of
                  this sub-family of receptor tyrases and carnases [sp] likely
                  obastoma [sp] where there's a autocrin loop [sp] for PGF.

                  And we're very much excited -- one synergy that I don't think
                  has been talked about is the PDGF still plays -- plays a very
                  important role in inflammatory diseases, where it's a major
                  player in the healing process, in response to inflammation,
                  and in certain diseases like hypatic [sp] cirrhosis, other
                  fibroidic diseases involving long and progressive renal
                  disease. PDGF plays a very important role, and we now have
                  orally active, very selected, PDGF receptor inhibitors, so
                  we're excited about the idea of sort of funneling these into
                  the programs that already exist at Millennium in terms of
                  inflammation and cancer.

                  And then finally, I mean, I think that one aspect that Mark
                  touched on, that hasn't been emphasized, is that as a
                  cardiologist and a scientist, if you just look forward in how
                  you're going to treat any disease, and this is particular true
                  of cardiovascular diseases, they are going to be personalized
                  in the future. We are going to understand which pathway one
                  needs to inhibit for a particular patient at risk. I mean, in
                  a sense, the stethoscope of the 1900s will become the kind of
                  transcriptional profiling and hapa type profiling that
                  Millennium will lead the world in. So, we're all very excited
                  about building that capability into the treatment of
                  cardiovascular diseases and rolling that in, actually, into
                  patient care directly and quickly.

M. Ho:            Thank you. If I may follow-up with another question -- what is
                  in the agreement with Schering-Plough and COR and is there any
                  stand still for Schering-Plough, and will this merger affect
                  the relationship going forward?

M. Levin:         The short answer is, no, it will not affect the relationship
                  going forward. We've had a wonderful relationship with our
                  partners at Schering-Plough. They were notified of this
                  transaction yesterday, after the board of directors approved
                  it. They congratulated us. Yes, there is a stand still, but
                  we're very good partners. We don't have to resort to a
                  contract.

M. Ho:            Thank you. Congratulations.

M. Levin:         Thanks a lot, Megan?

Operator:         Bill Tanner with SG Cowen, please proceed with your question.

M. Levin:         Hey, Bill.

Bill Tanner:      Hey, how are you guys? Maybe for you, Kevin -- I don't know if
                  you mentioned this - is there a collar on the deal, and I
                  wonder if you could comment as to a break-up fee? And perhaps
                  to follow-on on the last question -- is there the potential,
                  then, to perhaps restructure any kind of a Integrilin-related
                  agreement with Schering?

K. Starr:         There is no collar; this will be a fixed-exchange ratio deal
                  through closing. There is a break-up fee associated with the
                  transaction, and when we think about restructuring the
                  relationship with Schering, I just echo Vaughn's comments --
                  historically, we look at them as extremely strong partners and
                  look to continue that relationship the way we have in a very
                  strong way.

M. Levin:         Thanks, Bill.

B. Tanner:        OK. Could you comment as to the break-up fee, then?

K. Starr:         So the break-up fee is $75 million, and it has the standard
                  clauses in it, related to material, adverse changes, and it is
                  very ordinary in the way it's been constructed.

B. Tanner:        OK, thank you.

M. Levin:         Thanks a lot, Bill.

Operator:         Caroline Pratt with Needham, please proceed with your
                  question.

Caroline Pratt:   Hi. Congratulations.

M. Levin:         Hey, Carol, how are ya?

C. Pratt:         Good, thanks. I have two questions -- one is, at what point
                  during the negotiations did you learn about the revised
                  Integrilin guidance that would be coming out? And the second
                  question is, what does this do to your previous goal of 12
                  products in the clinic by year-end? Thanks.

M. Levin:         OK, Carol, the first -- you know, we started talking,
                  actually, with Vaughn and the team in September, and we've had
                  an ongoing discussion now, I guess, for about four months,

                                                                  Res. #20069850
                                                           Moderator: Mark Levin
                                                 December 6, 2001 / 7:00 a.m. MT
                                                                         Page 12


                  and one of the most important things to us on both sides of
                  this relationship has been, in all cases, coming forward and
                  saying, "What are the great opportunities," of course --
                  that's always easy -- but coming forward and talking about
                  what the issues are. So Vaughn and I and the team talked about
                  this a few weeks ago, we understood it, we have an
                  extraordinarily strong team inside, including John's expertise
                  in this field and others. We went out and we talked to major
                  academic leaders in the field across the country, across the
                  world, to really work with Vaughn and his team to better
                  understand what the numbers meant. And as we came through that
                  process, we continued to be convinced that this was a major
                  product for the future, continuing to grow at 30 percent. So
                  over the last few weeks, we heard about it, and we worked on
                  it, we understood it, and we see it as a pause and we would
                  expect significant growth next year.

                  To your second quarter, about 12 molecules in the clinic by
                  the end of the year -- that's going to be a stretch for us,
                  but let me tell you a little bit about where we are. A couple
                  things - one, we currently have nine molecules in the clinic.
                  We think it's going to be at least nine to ten by the end of
                  the year, and that doesn't include the IND that's going to be
                  filed within the next couple weeks. So between nine and ten
                  molecules in the clinic, one IND file, so you know, very close
                  to 11. One product on the market, which is certainly very
                  important, and then we're going to bring in probably some
                  late-stage pre-clinical molecules on top of that.

                  But I think also one of the things to do, which is important
                  here in this question, is to step back and look at
                  Millennium's major goals for the year. It was one to two
                  genomic targets in the clinic. That's done; we accomplished it
                  with obesity. Three-forty-one in Phase II; done.
                  Three-forty-one in combination trials in Phase I; done. Nine
                  seven-seven in Azmin [sp] Phase II; done. LDP02 in
                  ultra-cholitis and Crohn's in Phase II; done. Major metabolic
                  disease alliance; done. Revenue targets - we will hit. Cash
                  targets - we will hit. And in 12 molecules in the clinic -
                  we're going to get awful close, but we think we've done an
                  extraordinary job across all of those, and whether it's 11 or
                  12, we think at the end of the day, we've had really an
                  extraordinary year.

C. Pratt:         Great, thanks. Congratulations again.

Operator:         Meirav Chovav with CS First Boston, please proceed with your
                  question.

Dave Whiskey:     Actually Dave Whiskey [sp] here. Hi, guys.

M. Levin:         Hey, good morning.

D. Whiskey:       Just to follow-up and major some more clarity on the previous
                  question -- given the slowdown in Integrilin sales this year,
                  what specific changes in the market next year do you see that
                  will allow you to obtain 30 percent growth, how long will this
                  growth continue, and what do you forecast for peak sales?

V. Kailiean:      You know, there are two things you can do in this market to
                  get a product and category going again. One of the things that
                  has happened over the past three to six months is sort of a
                  retraction on the part of the two major competitors in terms
                  of market-building. That market-building has been left to us
                  and our partner, Schering-Plough. We are going to continue
                  that market-building through the Crusade effort. The Crusade
                  effort is really focused on ensuring adherence and adoption of
                  the ACCA/AHA guidelines at the emergency room level, where
                  these patients first present with chest pain. These guidelines
                  recommend the aggressive use of a 2B3N inhibitor in those
                  high-risk patients who are moving on to CAT. So we are going
                  to get that through at the hospital level.

                                                                         Page 13


                  That ends up in a real benefit, because as you know, when
                  guidelines are adhered to, patient outcomes are significantly
                  better.

                  Second, in the area of just competitive, the other way to grow
                  a business, as you've grown the pie, is to get a better piece
                  of the pie, is we've got a very aggressive program in place,
                  targeting those institutions that can really get a significant
                  economic benefit at a time when coated stents are coming out,
                  at a time when brachio-therapy [sp] is being utilized, at a
                  time when new closure devices -- all of these things are
                  adding costs to an intervention for cardiologists and for
                  institutions. The one thing they can do to significantly
                  reduce their expenses in that category is just switch from
                  Reapro [sp] to Integrilin. It's a significant cost savings in
                  the drug area in those institutions, and we plan to bring that
                  message each of the institutions in the United States.

M. Ho:            Vaughan, this is Maykin. Talking about that, what do you think
                  the impact of drug-coated stents will be the 2B3A category? So
                  you're expecting a switch from the more expensive Reapro to
                  the less-expensive Integrilin, but would they just decide to
                  eliminate the use of 2B3A? We've been hearing some rumblings
                  from some cardiologists in that regard?

V. Kailiean:      Why don't we ask another cardiologist? Charlie, do you want to
                  talk to the issue of drug-coated stents?

C. Homcy:         Yeah. I mean, I don't -- what I think I would say to that is
                  the fact -- people said that when stents first came out,
                  there'd be no systemic thrombotic events when the cardiologist
                  puts them in. In fact, the same problem applies to putting in
                  drug-coated stents. That is, that you deploy a drug-coated
                  stent, you induce thrombis, you induce myocardial infarctions
                  [sp] and the same kinds of problems occur. In fact, if
                  anything, the use of drug-coated stents will lead to
                  cardiologists tackling more difficult vessels, vessels that
                  they otherwise might not have tackled and doing multi-vessel
                  stenting. I mean, if you look at any of the clinical trials of
                  2B3A inhibitors, those are the kinds of patients, multi-stent,
                  multi-vessel, where myocardial infarctions in the procedure, a
                  pari-procedural [sp] period, occur at a much higher level, and
                  that's where the efficacy of 2B3A inhibitors really come out.
                  So in fact, I think that drug-coated stents will do two
                  things. More stents will be deployed in more vessels, more
                  difficult vessels will be deployed. In fact, I expect patients
                  who go to bypass surgery today in the future will go more
                  frequently to stenting, and I think 2B3A inhibitors will allow
                  that, will allow the cardiologist to put multiple stents in
                  comfortably, without the risk of creating myocardial
                  infarction. So I think actually the same story applies -- it
                  doesn't change.

M. Ho:            OK, thank you.

M. Levin:         Thanks, Maykin.

Dennis Harp:      Thank you and congratulations to both companies.

M. Levin:         Thanks. Good morning.

D. Harp:          -- you mentioned a number of programs to expand the
                  indications for Integrilin, and we've got a trial starting up
                  at STMI in the very near future. Could you give us some sense
                  of the timing of when those results might come in, and what
                  the incremental market -- target market size of those
                  additional indications might be? And then also,

                                                                  Res. #20069850

                                                 December 6, 2001 / 7:00 a.m. MT
                                                                         Page 14


                  could you just refresh our memory on the economic arrangement
                  with Schering-Plough in the U.S., Europe, and how that works
                  with Integrilin.

V. Kailiean:      Sure. The clinical results won't be available for about 18
                  months or so, possibly longer, in the setting, which is
                  basically a facilitated angioplasty setting, assessing whether
                  early use of a combination of pastos [sp] TNK, full-dose
                  Integrilin as compared to just full-dose Integrilin in
                  patients, both groups of patients moving rapidly on to
                  intervention, compare those two approaches to an early,
                  aggressive therapy in ST segment elevation MI. So the results
                  won't be out for -- for a period of 18 to 24 months.
                  Importantly, what this does, and you can't just look at the
                  400,000 to 500,000 -- I can't remember the numbers off the top
                  of my head -- patients that this brings in. What this will
                  hopefully do for us is make the use of 2B3A inhibitors in
                  peric [sp] use in all acute coronary syndrome patients,
                  regardless of whether they have ST segment elevation in mind,
                  or ST segment depression, and that, then, changes the whole
                  marketplace, so that when a patient presents who's high-risk,
                  before they try and determine whether they have ST segment
                  elevation MI or not, the answer is aspirin, heperin, and
                  Integrilin, so that's the goal there.

                  As it relates to Schering-Plough, the collaboration is set up
                  right now for a 50-50 profit share in the United States. We
                  basically take all the sales, throw it into a bucket, subtract
                  out cost of goods, marketing expense, some medical expense,
                  and divide the resulting margin between the two companies.
                  Around the world, outside the United States, COR receives a
                  double-digit royalty on any sales generated by
                  Schering-Plough.

D. Harp:          Great, thank you.

M. Levin:         Thanks a lot.

Operator:         Todd Nelson with RBC Capital Markets, please proceed with your
                  question.

M. Levin:         Good morning.

Operator:         The line is open to Todd Nelson.

Todd Nelson:      Excuse me, thanks. I apologize. Just a couple of questions --
                  I think most of them have been answered, but just to maybe
                  elaborate on a couple of things. I know that Mark, you had
                  talked about the synergies, and Vaughn also, and in combining
                  these two companies, maybe we could just talk a little bit
                  strategically about the feeding of the genomics-driven part of
                  the discovery pipeline into what presumably would be the
                  chemistry capabilities that COR has, and then Mark, given the
                  relationships, I think, that you mentioned you had with Buyer
                  [sp] and Lilly, over the course of the last few years, how
                  will you be restructuring those, if, indeed, you need to, and
                  then my second question is just very simply related to
                  manufacturing and Kevin had also mentioned some need not to
                  build things, and I wonder if that issue has been addressed
                  through this integration.

M. Levin:         OK, let me start with Buyer and Lilly -- those relationships
                  continue for the next couple of years. [inaudible] they're
                  very strong relationships in the cardiovascular area, one in
                  congestive heart failure, and one in arteriosclerosis, but
                  then at the end of two years, you know, we certainly look to
                  integrate these efforts, certainly in a much more synergistic
                  way, but at the same time, we can share ideas and biology, and
                  in many cases, actually share information and targets across
                  all the programs. So the Buyer Lilly relationship will
                  continue and they are very strong.

                  From an overall genomics effort, let me see if I can answer
                  your question -- Millennium, as you know, was originally built
                  on a genomics infrastructure. We've scanned the genome, we've
                  got several thousand druggable targets in front of us. We've
                  run those across a large transcription profiling effort,
                  looking for up and down regulation, tissue specificity across
                  the heart, across cancer tissues, et cetera, and much of the
                  same now has been done at COR in the genomics area, especially
                  in the whole cardiovascular area. So what this is going to
                  allow us to do is really combine this powerful genomics effort
                  with druggable targets and drive this into the chemistry area.
                  We're going to have over 300 people in drug discovery, from an
                  I2 put screening [sp] to lead optimization, and as Charles
                  mentioned, we see tremendous synergies in certain classes of
                  molecules. So for instance, the RTK kynase [sp] program from
                  COR, that kynase expertise is actually very important in
                  Millennium's kynase program, and a sub-segment of our genomics
                  program is to identify every kynase in the genome, to place it
                  either in cardiovascular disease or oncology or inflammation,
                  to find the right tissues, and then develop chemistry and
                  structural biology and computational chemistry around the
                  kynase area. So that's just one example of the synergies from
                  the genomics effort to chemistry and moving downstream into
                  structural and computational chemistry.

                  The third question, on the manufacturing side, could you be
                  more specific about the question there?

T. Nelson:        Well, just in the sense that as you go forward and have more
                  products emerging, you had talked before about potentially,
                  you know, how you're going to address manufacturing issues and
                  just very simply, does COR has manufacturing capabilities?

V. Kailiean:      No. This is Vaughn. COR does not have manufacturing
                  capabilities. We've long held the principle that our best
                  investment was in research, development, and
                  commercialization. We have not invested in the bricks and
                  mortar of manufacturing. Our Integrilin is made by two very
                  large chemical manufacturers; the bulk product is made in
                  Europe and it's filled and finished here in the United States,
                  on a contract basis. So while we bring the capability to the
                  virtual manufacturers, we do not bring bricks and mortar in
                  that respect.
